How to choose a free LLM API
Different projects need different free tiers. Here's a simple decision framework:
- Need the most tokens? — DeepSeek (500K one-time) or Plugsky (100K/day, unlimited duration).
- Need no card and no expiry? — Plugsky, Google Gemini, DeepSeek, or Groq. Skip OpenAI and Anthropic.
- Need OpenAI-compatible format? — Plugsky, DeepSeek, or Groq. Google and Anthropic use their own APIs.
- Need highest throughput? — Google Gemini (60 req/min). Plugsky is 10 req/min, fine for development.
- Need data privacy? — Plugsky, DeepSeek, and Groq never train on your data. Google and OpenAI require opt-out.
